Question

A multinational company placed orders for printing papers and writing pads. In the first order 5 carton of printing papers and 10 writing pads were ordered and total cost was Rs. 3000 and in the second order 10 carton of printing papers and 5 writing pads were ordered and total cost was Rs. 5250. What was the cost of one carton of printing paper and one writing pad?

Answer 1

Answer:

500 and 50.

Step-by-step explanation:

Suppose, cost per cartoon of printing paper was Rs x.

and cost per writing pad was Rs y.

for the 1st order: 5x + 10y = 3000;

5x = 3000-10y;

x= 600-2y;------1.

for the 2nd order: 10x+ 5y = 5250;

10(600-2y) +5y =5250;

6000 - 20y +5y =5250;

750 = 15y;

50 = y

then x=600-2*50;

x=500;

cost per cartoon of printing paper was Rs 500 and per writing pad was Rs 50.
